On the other hand, the Wikipedia article contains an unsourced statement:
Police departments counter that while Tasers were used to subdue these individuals, their in-custody deaths were unrelated to their encounter, and could have likely been caused by more traditional police impact weapons (like batons).
Further, Taser International CEO Rick Smith claims is reported to have claimed:
police surveys show the device has saved 75,000 lives.
Does the use of tasers by the police lead to an increase in police killings (as implied by the linked blog), or does it lead to a decrease (as claimed by the Taser International CEO)?
In response to @JoeWreschnig's comment, the saved lives comment might refer to shooting with a taser instead of shooting with a gun. The relevant subquestions are therefore:
- What is the conditional probability of being killed when being shot by a taser?
- What is the conditional probability of being killed when being shot by a police gun?
- In what fraction of lethal taser shots was the taser shot used instead of a gun shot?
- In what fraction of lethal taser shots were other alternatives available?
I think that with these sub-questions, the main question can be answered.
